Now shouting is just plain rude, but in keeping with the tone of your responses , so I am not surprised.
I EMPHAZIZED and not shouted (offcourse you'll take it as the way you are) because you were missing major chunk of what i said and just pressurizing over elements that may prove me wrong.
Yes it is there is no such thing as "Deep Trodden" rooting. I Simply asked you to explain what that meant and you said "it just means rooting", therefor you made it up. I am not suggesting that coining expressions is a bad thing but your terms are a little confusing.
You have the tendency to talk your own stuff and recite it till the end, I told you that every rooting is Deep Trodden because you get deep into it ,its that simple but people like you looking for tracking people rather than get any original knowledge make such lacy and stretchy useless talks
I suggest that you take a leaf out of your own book and read the post and its thread before posting. especial in light of the fact that you said that rooting is done to gain access to the USB port but the OP clearly states that he has this already.
I suggest again to understand what I write, you yourself are leaning off the topic, The OP wants to do Serial commuication and you took the OTG pathway all the way, I talked about rooting maybe needed for getting the Serial ports emulated. I told him that it maybe needed.
Try just posting stuff that helps the OP rather than making out your own understanding of what the other person means actually.
